Melanonychia striata L60.8
Striped black coloration of the big toe nail. The finding is unchanged since > 1 year. Here striped onychomycosis due to mold infestation of the nail. Diagnostic evidence is the normally colored proximal stripe above the nail dyschromia (see explanatory figure and reflected light microscopy).
Nail hematoma T14.05
Nail hematoma: after a well remembered trauma, about 3 weeks ago, acute red coloration of the toenail.
Glomus tumor D18.01
glomus tumor. isolated, bluish-red, subungual localized, spherically protuberant, firm nodule. typical, lancing shooting, extremely unpleasant pain (e.g. in cold and touch)
Nail hematoma T14.05
Nail hematomas: bilateral discoloration of the big toe nails, sharply limited to the sides and to the front.
Meese cross bands L60.8
Meesche transverse ligaments: 56 year old woman. 3 months before the present picture was taken, the patient had severe bronchitis. The symmetrical white transverse ligament of all fingernails indicates the temporary, systemic disturbance of the organism. Picture from the collection of Dr. med. Eva Kämmerer
Splinter hemorrhages
Splinter hemorrhage: Reflected light microscopic image with a few days old splinter hemorrhage.
Nail hematoma T14.05
DD: Nail hematoma - here Melanonychia longitudinalis: Typical finding of a melanocytic pigmentation of the nail. Melanon grows in stripes, starting at the site of pigment formation (here the nail root is not visible) to the front. This finding is not observed in a nail hematoma. Note: the nail matrix shows a dark discoloration at the front edge of the cut (pigment is embedded in the nail matrix).
Melanonychia striata L60.8
Melanonychia striata longitudinalis (2): control finding in 2016. widening of the longitudinal pigmentation of the nail plate. clear Hutchinson sign (pigmentation of the nail fold)
Melanoma cutaneous C43.-
Differential diagnosis of discoloration of the nail: Melanocytic neoplasms of the nail matrix always lead to longitudinal striation of the nail plate.
Subungual melanoma C43.L
Melanoma malignes subunguales: Nail with stripy and periungual brown markings (Hutchinson's sign) in acrolentiginous malignant melanoma under the nail plate and in the nail bed (see Levit's ABC Rule)
Half-and-half nails L60.8
Half and half nail: Zonal, slightly blurred white coloration of the proximal and brown coloration of the distal nail plate; no underlying disease known.
Striated leukonychia L60.8
Leuconychia striata: White horizontal stripes of the nails in the presence of the Sezary syndrome; above the white bands, flat, discrete leukonychia.
Glomus tumor D18.01
Glomus tumor. solitary, painful defect formation of the nail, accompanied by stabbing pain that occasionally radiated into the upper arm.
Splinter hemorrhages
Splinter hemorrhage: Fresh splinter hemorrhage in previously known progressive systemic scleroderma.
Half-and-half nails L60.8
half and half nails. white coloration of the proximal half of the nail plate and sharply defined red or brown coloration of the distal half of the nail plate. finger and toenails are affected. the milky white coloration of the free-standing nail plate indicates a simultaneous scleronychia.
Melanonychia striata L60.8
Melanonychia striata longitudinalis (course): Initial findings in 2006, control findings 3 years later; the brown longitudinal stripe, persisting since about 2004, has almost completely receded within a period of 3 years except for a discrete residual pigmentation (arrow).
Sézary syndrome C84.1
Sézary syndrome: transverse white bands and discrete leukonychia in existing erythroderma.
Splinter hemorrhages
Splinter bleeding: in generalized psoriasis with large oil stains and thickening of the nail plates.
